>>> What would you recommend to use for dye? Aniline-21 or Aniline-76?
You may used both, but ultimately you will need a “coating” dyestuff with Aniline-76 instead of a “staining” dyestuff Aniline-21. If both are to be used, even out the color difference as much as possible with Aniline-21 and Aniline-76 the final touch up. Surfactant-3.6 is used prior to Aniline-21 to check for surface tension or blotchiness with an even appearance without blotchiness to ensure even Aniline-21 staining or absorption. Any surface excess is rub away. Aniline-21 is a below surface dyestuff and Aniline-76 is a surface dyestuff.
>>> It’s a dark grey color. Could we just use black aniline 76 and clear aniline to get the desired tone?
Dark grey can be achieve with Black and Clear - maybe black and clear ratio 6: 4, 7: 3, 8: 2 or 9: 1 test it out for satisfaction.
>>> Or do I have to order a custom color match?
You may, will need a color sample as usual.
